MEANS FOR HEATING AUTOMOBILES AND THE Specification of Letters Patent.

Patented Oct. 22, 1907.-

Application filed December 26. 1906. Serial No. 349.398.

' tomobiles and the Like, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings.

My invention relates to heating. apparatus for automobiles and the like and more particularly to means for utilizing the exhaust gases from the explosive engincs of siich vehicles in such manner as to permit any desired proportion of such gases to be diverted into the heater without interfering with the operation of the muffler or engine and without discharging into the car any of the gases supplied to the heater. I accomplish these results by means of the apparatus disclosed in the drawings, wherein Figure 1 represents a side elevation of an engine, muflier, and heater and so much of an automobile as is necessary to show the manner in which my invention is applied thereto; Fig. 2 represents anenlarged sectional detail of the valve and connections by which the exhaust may be diverted either partly or wholly into the heater connection; and Fig. 3 represents a plan view of one form of my heater.

1 represents an automobile of any approved construction having therein a suitable number of cylinders 2 discharging into a common exhaust pipe 3, connected with a muflier 4.

Intermediate of the engine and muffler, the exhaust pipe is provided with a tee 5 to which is connected the pipe or connection 6 leading to a heater 7, which is located within any suitable portion of the body 8 (represented in dotted lines). The heater is shown as a radiator having an outlet pipe or connection 9 communicating with the pipe 3 on the inlet side of the mufller.

' The tee is provided with a valve 10 having therein two ports 11 and 12. In Fig. 2, the valve is shown in three positions. In the first position, represented by full lines, ports 11 and 12 are in register with branches 13 and 15 of the tee and the entire exhaust tee is being diverted into the heater inlet pipe or connection 6.

. In the second position, represented in dotted lines, the

valve has been turned so that the partition 16 partly uncovers"branch 14"and partition 17 partly covers branch 15, causing a portion only of the exhaust to be diverted into the heater, the remainder flowing directly to the mufiler. In the third position, represented in dotted lines, the valve has been turned until partition 16 entirely uncovers branch 14 and partition 17 entirely covers branch 15, enabling the exhaust to flow directly to the muffler. The width of partitions 16 and 17 and of ports 11 and 12 is such as to permit port 11 to be in continuous communication with branch 13 while port 12 is in full communication with either of branches 14 and 15 or in partial communication with both of said branches. The valve is provided with a lever 18 and an operating rod 19 therefor.

The heater which I prefer to employ is a single loop, one branch 7 whereof may extend transversely of the vehicle body in frontof the bottom of the front seat and the other branch 7 whereof may extend transversely of the vehicle body between the front and back seats, said branches being connected by the longitudinal branch 7. The cross-sectional area of this loop is such as to enable the exhaust gases to pass freely therethrough without the production of any undesirable back pressure, such as would stop the engine, particularly when the same is turning over preliminarily to starting the vehicle. The particular shape and construction of the valve contributes to this result, as it permits the exhaust gases to be diverted without friction to either or both of the connections 14 and 15 and without any material throttling of said gases.

To enhance the heating effect, the branches 7 7 and 7 may be provided with flanges 20.

When it is not desired to use my heater, as in the summer time, it may be readily disconnected, upper branch of tee 2l closed and, by giving a half turn to tee 5 to cause connection 15 to be directed downwardly, as indicated in dotted lines, Fig. 1, the valve may be used as a cutand location of the valve enables the amount of heat supplied to the heater in the vehicle body to be readily I controlled and adapts the same to be used as a cut-out valve when the heater is not needed.

I claim:

1. The combination of an engine, an exhaust pipe therefor, a muffler, a heater, an inlet pipe or connection extending between said heater and said exhaust pipe, an outlet pipe or connection establishing communication between said heater and the muffler, and a valve at the junction of the inlet pipe or connection and the exhaust pipe, said valve having an outlet port adapted to register either partly or wholly with said inlet pipe and the portion of the exhau" pipe leading to the muffler and having an elongated inlet port adapted to register continuously with the portion of the pipe extending toward the engine while the outlet port is in communication witheither or both of its pipes, substantially as specified.

2. The combination of an engine, an exhaust pipe therefor comprising two sections, a muflier, a tee having its opposite branches rotatably fitted to the exhaust sections, a heater having an inlet and an outlet pipe or connection, the former being detachably connected with the third branch of the tee and the latter communicating with the muffler, and a valve in said tee adapted in one position to divert the exhaustv gases through the third branch of, the

tee and in another position to discharge such gases directly into the pipe section extending to the mufiier, sub stantially as specified.

3. In an automobile, the combination of an engine, an exhaust pipe, at mutller, a heater, an inlet pipe extending between said exhaust pipe and heater, an outlet pipe extendinghetween said heater and exhaust pipe, and a valve at the junction of the inlet pipe and the exhaust pipe. said valve having an outlet port adapted to register either partly or wholly with the said inlet pipe and the portion of the exhaust pipe leading to the inniiler and an elongated inlet port adapted to register continuously with the portion of the pipe extending toward the engine while the outlet port is in communication with either or both of its pipes.

4. In an automobile, the combination of an engine, an exhaust pipe comprising two sections, a mulller, a tee having its opposite branches rotatably fitted to the exhaust pipe sections, a heater having an inlet and an outlet pipe or connection, .the former being detachably connected with the third branch of the tee and the latter being detachably eonected to the exhaust pipe at a point between the tee and the muffler, and a valve in said tee adapted in one position to divert the exhaust gases through the third branch of the tee and in another position to discharge such gases directly into the pipe section extending to the muffler.

In testimony whereof, I hereunto aiIix my signature in the presence of two witnesses.
